To allwhom it may concern: screw 3, and the latter rotated to conveyBeitknovm that LEMiLn DOB-DELATTRE, material through the casing 4 overthe rea resident of Liege, Belgium, a subject of the ceptacle 1, thecompartments 11, 12, 13, 1% King of the Belgians, engineer, haveinventand of said receptacle will be successively 5 ed certain new anduseful Improvements in 1 filled. When the receptacle 1 is completelyApparatus for Obtaining Intimate Mixtures, filled or the desired amountof material deof which the following is a full, clear, and positedtherein, the supply of material is exact description, such as willenable others cut-off; and thereafter the conveyers 5 and skilled in theart to which it appertains to 8 are started and the direction ofmovement of the feeding screw 3 reversed. The conpresent inventionrelates to an appaveyer 5 operates to remove the material ratus formixing materials and has forits from the receptacle 1, each of thec0mpartobject to provide means by which materials ments in saidreceptacle simultaneously disol" different character or of dillerentdegrees charging u on the conveyor and thereby the 15 of fineness may bethoroughly mixed. several su stances previously contained n in theaccompanyingdrawing, Figure 1 is said receptacle will beprlmarily'inixed as a irontview ofan'apparatus constructed in they aredelivered to the screw conveyer 8.

2. An apparatus l'orthe purpose described comprising two receptacles,nreans lor con- I veying material from the lower endot' eitherreceptacle to the upper end of the other includlng a reversible conveyoradapted to deliver material to one receptacle when moving in onedirection and to the other receptacle when moving in the oppositedirection. 3. An apparatus for the purpose described comprising tworeceptacles, a reversible l'eeding device adapted when moving in onedirection to deliver material to one rr-rccptacle and to delivermaterial to the other receptacle when moving in the opposite direction,independent conveyors each adapted to receive material lrorn one of ther-er -eptacles,

an elevator adapted to deliver material to the feeding device, and meansfor transport ing material from both said conveyors to the elevator.

4i. Aruapparatus for mixing substances, comprising two receptacleshaving vertical compartments, a reversible screw conveyor for feedingthe substances to either of said arranged to receive material from theelevator, and a controlling device by which receptacles, means foremptying said receptacles by horizontal layers, .an elevator deliveringto said screw conveyor, and means l'or transporting the material of saidlayers to said elevator.

5. An apparatus for mixing substances, comprising two receptacles havingvertical con'ipartn'icnts, means for feeding the substances to thesuccessive compartments of by said double screw conveyor and deliveringto said reversible screw conveyor.

7. An apparatus for mixing substances, comprising two receptacles havingvertical compartments, a reversible screw conveyer" feeding thesubstances to the successive com partnrents of either receptacle,alternately operating transporters emptying said receptacles in turn byhorizontal layers, a double screw conveyor receiving from one 01 saidtransporters, an elevator ted by said double screw convey-er, saidelevator normally delivering to said reversible screw conveyer, and apivoted trap movable into the line of delivery of said elevator.

b. 'An apparatus for the purpose described, comprising two receptacleseach having its interior divided into a plurality of verticalcompartments, a conveyor traveling beneath each receptacle and adaptedto simultaneously receive material, from all of the compartmentsthereof, an elevator adapted to receive material from both saidconveyors,

and deliver the same above the receptacles, 'means for transportingmaterial delivered by the elevator to the several compartments of onereceptacle successively when operated in one direction, and similarly tothe other receptacle when operated in a dill'erent direction, and meansfor causing said elevator to deliver the material at a point outside ol'both said receptacles.
